Abstract

The invention discloses a power transmission line vertically-arranged lead switching-off and grounding connection type and method. The connection type comprises a pair of switching-off points arranged in an upper lead tension direction, wherein the two switching-off points are connected through employing a tension insulator, grounding wires are led out at the switching-off points through tension wire clamp leading boards, the grounding wires naturally sag under the gravity action, and the grounding wires are perpendicularly connected with an upper lead, a middle lead and a lower lead. Electrical connection in one same lead tension direction is switched off through employing the tension insulator, inter-phase insulation is guaranteed through utilizing the inter-phase insulator to directly form grounding of the line switching-off points, and a safe, reliable and flexible grounding mode is realized. The connection type is advantaged in that switching-off and grounding at any position of the vertically-arranged lead can be directly carried out, flexibility and reliability are realized, establishing a tower is not needed, a mounting speed is fast, the power failure time is short, and cost is substantially saved.

Description

technical field [0001] The invention relates to the electrical technical field of power transmission lines, in particular to a connection type and method for vertically arranged conductors of power transmission lines to be disconnected and guided. Background technique [0002] At present, the disconnection and down-conduction of transmission lines is a commonly used type in the design of power grids, especially for lines in urban areas. At present, the common way of breaking and leading the transmission line is to build two base terminal towers near the breaking point, and the overhead line is broken and led down through the terminal towers. [0003] The technical problems of the above-mentioned transmission line disconnection lead are: two base terminal towers need to be built, which increases the cost of implementation and cannot be disconnected at any position, the construction time is longer, and the power outage time is increased. [0004] To sum up, in the prior art, ...
